IMPROVEMENT IN KNITTING MAGHINES.

I-La dgetnle referat tu in that lettas ttent ma mating part uf tigtsami.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL V. ESSICK, of Mansfield, in the county ofRichland, and State of Ohio, have invented a newand useful Illiprovementin Machine for Knitting; and I do hereby declare that the following is afull and 'clear description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon. i

My invention relates to certain improvements in machinery for knitting,as hereinafter specified and represented. In reference to theaccompanying drawingsv Figure 1 is a perspective view, representing theimproved knitting machine with all its working parts arranged in orderlfor operation.

Figure 2 is a sectional View of the main partof the machinery, showingthc parts which form the stitches and fix them upon the cogs of wheel J.I

Figure 3 is a. sectional view of the main sliding piece.

Figure 4 is a sectional view of a lever, the point N of which strips olithe old stitch and forms the new one on each cog of the wheel J. i

Figure 5 is a sectional view of spring D.

' L is a needle,which carries the thread over the cogs of wheel J, andthrough the stitch formed on the cog of said wheel J. This needle L isbevelled at the point on the top, and is straight on the under side. Ais a lever, the point N of which strikes the inside of the eogs of wheelJ, thus securing the stitch formed on the cog of said lwheel J, and bythe backward motion of said lever A the said stitch is drawn ofi` thesaid'cog, and at the same time the new stitch is formed on the said cogby being fixed on the cog while the old one is stricken oi by the pointof the lever A. D is a spring, working in connection with lever A insuch a way that its point Strikes between the thread and the needle'L,and holds the thread while the needle is drawn backward, thus forming a.new stitch. When this is\done the lever A and spring D, being connectedare drawn back together,

'Which backward motion strikes oii the old stitch and forms the newstitch upon the cog of wheel J. Pis a spring, which holds down'the leverA. T is a rod, connecting the main sliding piece B with the crank N. Eis a. screw, surrounded by a spiral spring, which tightens the threadand causes the machine to knit a tight or loose web by means of thetightening or loosening of the screw, the thread being caused to passbetween the said spring and the body of the machine in which thescrewworks. R is a rim, which is fastened to the main plate or body of themachine, and so arranged as to be movable,-in order that diiferent sizesmay be substituted, and is used for holding the stitches on wheel J. Fis a ratchet, which turns the cog-wheel J, being con- -nected with themain sliding piece B. H is' a square wheel, with a notch at each corner,which works in the lever A, carrying it forward over the stitches. M isthe main plate, to which the machinery is attached.

The operation .of my invention may be described as follows: The machinebeing iirst attached to a table or stand by means of a clamp, by theturning of th'c crank V all the working parts are set in motion. Theneedle L is carried forward through the stitch formed on the cog ofwheel J. When it moves a suiicicnt distance the point of spring Dstrikes between the thread and the needle, the said point holding thethread until the needle is drawn back out of the way, when the pointof'lever A draws oii the old stitch, and forms the new one 'on the cogby means of the backward motion of said lever A, the lever being drawnwith thc main sliding piece B. The ratchet F, by the forward motion ofmain slide lB, is caused to 'move the cog-wheel J one cog at the takingofevery stitch.

What I claim as my invention, and desire 'to-secure by Letters Patent,is-

The needle L, constructed as described, the spring D, the main slidingpiece B, the lever A, the wheel and rim J and R, the thread-holder E,the ratchet F, the spring P, and the cornered wheel I-l, all arrangedand operating substantially as described and for the purpose set forth.

In testimony of which invention I hereuntofset my hand in presence of-SAMUEL V. ESSICK.
